By operating the second motor 9, the second lead screw 10 rotates, that is, the processing sliding frame 11 drives the processing box 13 to approach the surface of the circuit board. The surface of the circuit board can be dusted first, that is, the cleaning part 34 is controlled to move by the cleaning electric cylinder 33, and the cleaning part 34 performs the dust removal operation; further, by operating the angle motor 17, the rotating cylinder 15 flips, that is, drives the circuit board to flip to realize the treatment of different surfaces.
